Tbh I did not say at all that they need limit it to raids only.
I said, reign its power level to some normalized level outside of raid instances. So you can continue to “enjoy” the overtuned raid trinkets within raids and everyone else can remain unaffected by it.
It would still work, but not on 100%.
Actually we already had something similar:
The secondary equip effect on the Antorus trinkets notes that “When empowered by the Pantheon…”, such as ‘Aman’Thul’s Grandeur’ on Aman’Thul’s Vision or ‘Khaz’goroth’s Shaping’ on Khaz’goroth’s Courage will only function within the Antorus raid once it is live.
Something similar could be used as a foundation to address the raid trinket issue once and for all.
Perhaps if necessary, it could be extended to m+ as well, tho m+ rarely has such appallingly overtuned items, but I would have no issue with using it wherever it makes sense.
But it does not make sense to make them as oppressive as they usually are. It also completely invalidates the item level system, because its x item level only on papper. In the reality its rather 1.5x.
